Is my HDD completely dead?

WD5000AAKS 500GB ~3.5 years old

It works fine last night ~10 hours ago. Several days before though, it would keep saying "error loading operating system" from time to time. I would have to press reset button, and it would boot fine.

Right now, BIOS load fine but shows blank on where HD should be. When it tries to boot OS, it stalls for about 20 sec before it tries to boot from CD

I tried putting in win7 OS cd to format it, but it did not detect any HDD.

I put the HD my brother's PC by itself, and it stalls with blinking cursor on top left on screen. Also tried using 'detect HD' feature in BIOS, but still shows blank.

Then I put the HD in together with working HD, same thing. I even try to boot the OS exclusively from the working HD and it still stalls.

Any ideas?

  1. Try changing slots where your are connecting the drive on Mobo, then try your faulty drive at a friends system to ensure if its dead.
  2. When my 40GB maxtor died it was the same thing, woudlnt always load OS needed to reboot for it to regonize it. Chance are its dead but always a good thing to try it on a different motherboard. If it is the same kind of drive failure I had (expanded head) you could freeze it for 24h and try to recover some data. It worked for me but it will only work with one type of drive failure.
